High-Bandwidth Interrupt Transfers (Three Packets per Microframe) in Windows® XP - KBA93229

Version: *A



Is it possible to implement high-bandwidth interrupt transfers (three packets per microframe) in Windows® XP?



No, the Windows XP Enhanced Host Controller Interface (EHCI) driver does not support high-bandwidth interrupt transfers. However, it does support high-bandwidth isochronous transfer, so an isochronous endpoint configured for three packets per microframe (3*1024 bytes) can be used for such an application.
